This control combines a list-box control with an entry-field control. It allows the user to place the selected item from a list box into an entry field.
The COMBOBOX statement, which you can use only in a DIALOG or WINDOW statement, defines the text, identifier, dimensions, and attributes of a control window. The predefined class for this control is WC_COMBOBOX. If you do not specify a style, the default style is CBS_SIMPLE, WS_GROUP, WS_TABSTOP, and WS_VISIBLE.
